I think that Free42 should now be renamed Free42s, where the "s" suffix stands for "supercharged."

The dynamic stack feature is great for the Free42 emulator, but it is even better on the DM42 with its multi-line display. This is why I urge the SM crew to update the DM42 with the new version 3 of Free42, even it there are no current updates for the DMCP OS or other DM42 features and bug fixes. I...

Thanks ! Apparently, it can also be configured to emulate the HP 49g+, but I chose to keep it as the HP 48GX. My physical calculator is an HP 48SX.

This is what it looks like in Firefox on my Mac:

Yeah, that's much better than on my 25" FHD monitor in Chrome. I also made the same mistake and first though you had 1/3 instead of sqrt(3).

Both -2 and 1+i sqrt(3) are valid roots. In fact, there are three valid roots, the third being 1-i sqrt(3). If you look at this in polar form, you see that all three numbers have the same magnitude of 2, and with phase angles of 0, 60 and -60 degrees respectively. So, in reality, the calculator is g...

I was a Teenager when I bought my HP41CV. At first there was no money left for the Math Pac.

I'm amazed that you could even afford an HP41CV at that time ! I was 26 when I bought my HP35, and it cost nearly half a month's net take home salary.

Actually, hyperbolic functions are included as part of the Math Pac module that is included with the DM41X. Also, I prefer to assign them to the SIN, COS, TAN keys in User (USR) mode.

So the result with Free42 is 8.999999999999999999999999999937534. Amazing !

There is a website https://www.rskey.org/~mwsebastian/miscprj/forensics.htm that describes an algorithm intended to help identify the underlying calculator processor that is being used in a particular calculator brand and model. Often times the chip set from a particular manufacturer was the basis f...
